The Canadian Lung Association expressed disappointment in federal Health Committee Chair Joy Smith"s stance on the issue of Air Canada and WestJet"s policy to allow pets to travel in the passenger cabin of airplanes. The Lung Association launched an online campaign for pet-free flights in July following the decision by Air Canada to join WestJet in offering pet-free flights, despite the serious risks it presents to passengers and crew with asthma, COPD and severe animal allergies.
